# 1. 类是相似功能的集合体.



# 2. 类 你要站在上帝的角度去考虑问题.


# 类: 具有相似功能和特性的一类事物.
# 对象:类的具体体现.

# 一定要有宏观的概念,区分类与对象.

# 类的第二个优点: 你要站在上帝的角度去考虑,类一个公共模板,对象是从这个公共的模板产出的.


# 结构上分析:

    daily = '学习'
    examination = '考试'


    def work(self):
        print('每天要上课')

    def homework(self):
        print('家庭作业')



# Human 类名要具有描述性,类名首字母大写,类名不宜用_
